PROBLEM TO BE SOLVED: To provide a display cell shape having high luminous efficiency of phosphors and high luminance with low power by providing multiple main discharge recesses having phosphor layers on the curved inner walls on the front substrate side surface. SOLUTION: Display electrodes 6, 6a, bus electrodes 7, 7a, a dielectric layer 8 having the film thickness of 0.002-0.03mm, and a protective layer 9 having the thickness of 0.0001-0.002mm are formed on a glass substrate 4 to obtain a front substrate 1. A photosensitive film 1120 is laminated on the surface of a glass substrate 5, it is exposed, developed, washed with water, and dried, the glass substrate 5 is machined by the sand blast method to remove the portion of the glass substrate 5 not covered by the film 1120, and recesses having the depth of 0.08-0.3mm are formed as main discharge spaces 100. Address electrodes 10 and phosphor layers 12 are provided on the recesses to obtain a back substrate 2 having barrier ribs 11 and the phosphor layers 12. The front substrate 1 and the back substrate 2 are fixed so that the display electrodes 6 and bus electrodes 7 are made perpendicular to the address electrodes 10. |
